3SMAJ5938B-TP from MCC(Micro Commercial Components), in a DO-214AC(SMA). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode, the end of the SMA (DO-214AC) body carrying the cathode mark; the 36V (VZ at IZT=10.4mA) zener is reverse biased with this pin positive. |
| 2 | A | passive | Anode, the lead opposite the cathode mark; maximum forward voltage is 1.5V at IF=200mA. |
